When you switch networks you will need to change the SMTP server to the new network. Most ISPs do not allow traffic on port 25 (the port that SMTP uses). The only way to get around this would be to setup a secure SMTP server which uses a different port number and requires authentication so that only authorized people can send email through that server.
